Synthesis and Characterization of the Nano Semiconducting Material Cadmium Sulphide

Abstract:

In this work, CdS nano particles were synthesized using aqueous precipitation method; This method is simple, fast and can be carried out at room temperature. Various techniques like X-ray powder diffraction and UV-visible absorption spectroscopy are used for the structural characterization like electron density distribution and estimation of inter atomic distances between the atoms of the nano particles. The optical band gap of this material has been determined in order to establish a relationship between energy gap of bulk and nano materials.
